Dr. Le Sage has been practicing as an emergency physician for more than 30 years at the Hopital de l’Enfant-Jésus du CHU de Québec-Université Laval. She is also a clinical researcher at the Research Center of this institution and at VITAM Research Center.
In addition, she is a full clinical professor at Université Laval Faculty of Medicine and has been a member of the Program Committee of Emergency Medicine for over 15 years. Holding a PhD in epidemiology, she never stopped to be involved in the development of a research program in emergency medicine at Université Laval. She has also been a member of the Clinician Scientist Program of the Royal College of Physicians and Surgeons of Canada at Laval University.
To date, her research work emphasized on emergency and trauma medicine, and her research program – PoCS Research Program – has focused on concussions (mild Traumatic Brain Injuries) and the prognosis factors that could predict long-term evolution after such trauma, including the possibility of using biomarkers.
With her dual expertise (clinical and research), she is regularly involved as a medical expert on various committees at MSSS and INESSS. Indeed, the importance of disseminating best evidence knowledge has always been at the heart of her concerns.
At the twilight of her career, Dr. Le Sage recently changed her focus and will now devote her full clinical time working in medical assistance in dying (MAID).
